WILLIAM H. EDWARDS, OF GRAND RAPIDS, MICHIGAN, ASSIGNOR TO THE PROUDFIT LOOSE LEAF COMPANY, OF GRAND RAPIDS, MICHIGAN, A CORPORATION. OF

LOOSE-LEAF BINDER.

To all whom it may concern.

Be it known that I, WILLIAM H. Enwanns,

a citizen Ofthe United States, residing at Grand .Rapids, in the county of Kent and State .ofMichigan, have invented new and useful Improvements in Loose-Leaf Binders, of which the fOllOWiIlg is a specification.

The'present invention relates to loose-leaf binders, and its object is to provide an improved wear late between the cover of the binder and t e leaves therein contained;

and further,;.to provide such a wear plate comprising a folded strip readily attachable toa base, as the fly-leaf of the binder.

This object is attained by, and the invention finds preferable embodiment in, the structure hereinafter described and illustrated by the accompanying drawings, in which Figure l is a fragmentary side view of a loose-leaf binder; 7

Fig. 2 is a sectional view of the same taken on a plane corresponding to line AB of Fig. "1;

Fig. 3 is a view in perspective of a portion ofthe-fly-leaf or base and the folded strips attached thereto; and

Fig. 4 is a view in perspective of one of saidstrips partially folded.

Inthe embodimentofthe invention chosen for illustration by the drawings and for detailed description in the'body of this specification, theloose-leaf binder shown has a pair of covers 1, 2, connected by flexible and preferably .resilient leaf-holding members extending betweenthem, as the spring steel bands3, 4, which ass through suitable slots (not shown) in -t e binding edges of the removable leaves 5 in the well-known manner,-=and extend under clips 6 on the inside of covers to points of secure attachment, as the lugs 7 on the covers which engage holes 8 in the bands.

The bands may be adjustable longitudinallyandrelatively to-the binding edges 9 of the covers .by suitable means, as by insertingthelugs into oneor another of the holes disposed in-the bands longitudinal direction. These clips 6 are positioned inwardly from the binding edges of the covers thus connecting the bands to-the covers at a short distance from said binding edges.-

Asthe covers are swungto open or close thebinder, their binding edges have a turning movement en the parts between the cov- Specification of Letters Patent.

ers, which tends to wear such parts and to mar the leaves if these binding edges engage the same. To obviate this, I provide an im proved wear plate 10 comprising a base 11 which may be that portion of the fly-leaf 12 which is adjacent to its binding edge. The wear-plate comprises also a strip 13,'as of suitable bendable metal, foldedorbent longitudinally around the outside edge of said base and embracing its opposite sides. 'A, portion of the outer fold 14: of this strip is inclined outwardly at 15 toward the binding edge of the device, on which inclined portion the binding edge of the cover engages in its turning movement. Toward the inside edge ofthe outerv fold, such foldhas a portion 16 which contacts with the base, and another portion 17 which thus contacts with the base adjacent its outside edge. One of the folds has a flange 18 which turns over the inside edge 19 of the base. The strips are secured to the base by suitable means, as by the spurs 20 formed integral with the other fold of the strip and which arepressed into the base. The strip is formed with par: tially closed folds as shown .in Fig. 4, and is passed over the outside edge of the base, whereuponthe folds are pressed together, theflange 18 extending overand contacting with the insideedge ofthe base and the spurs being pressed into .it.

The strips are made in sections of suitable length to be attached in alined relation, and with spaces between them, to allow the passage of the leaf-holdingmembers through suitable slots 21 in the bases and between the ends of the strips, as shown in Fig. 3.

As stated, the bases arepreferably portions of the fly leaves themselves and are connected to the body of such fly leaves by fiexible'and thinner portions 22.

It will be seen thatas the covers are closed their binding edges .9 ride up on the inclinedv portions 15 o f the strips and thus, the cow ers tend to remain "closed owing to the fact that the leaf-holding members depart from the inner sides of the covers at a distance from their binding edges. These inclined portions also raise the covers so that more room for adjusting means on the cover and near its binding edge is provided: and furthermore, inasmuch as the strip is firmly secured to the base, which has considerable width, the strip is prevented from tiltin on a longitudinal axis, and the binding edges of the covers are in their turning moveflexible member extending between thecovers and connected to their inner sides at a short distance from their binding edges; a wear plate adapted to be engaged by the binding edge of a cover in its turning movements, and comprising a base having an opening through which passes the leaf-holding member, and a strip folded longitudinally around the outside edge of the base and embracing its sides and securely attached to the base and extending inwardly between the-base and the binding edge of the cover.
